Dual Duty Indigo

Corespun sewing thread that gives a unique faded effect on denim

  • ShopCoats
Coats Dual Duty Indigo is dyed with natural indigo from the leaves of the Indigofera tinctoria plant.

It is a high-tenacity corespun thread delivering outstanding sewing performance and maximum durability. During the denim wash process, the thread fades to give each denim garment sewn with Dual Duty True Indigo a truly unique finish.

After sewing, the saturated color of the thread is washed down during the denim wash process to give a unique faded effect so every denim garment sewn with Coats Dual Duty True Indigo is truly unique. The polyester filament core of Dual Duty True Indigo offers excellent strength and durability, while the long staple cotton wrap ensures excellent sewing performance and protects the core from needle heat.

In the denim world the magic of 'Iro-ochi’ or 'Atari' happens at the wash process, but can also destroy the seams if the sewing thread is inferior quality. This means you get expensive and unsightly repairs after wash. With Dual Duty True Indigo sewing thread you can banish costly after wash repairs and focus on creating high performance iconic denim pieces which will last a lifetime.
